DRAFT-EQUALIZER rosaeaa,

To all whom t may concern: l

BeV it known that l', WINFIELD Soort NICHOLS, a citizen of the United States, re-

siding at Plano, in. the county of Kendall and State of Illinois, have invented new and vuseful Improvements in Draft-Equalizers,

of which the following isv a specification, reference being had to the accompanying drawings, Jforming a. part thereof.

The purpose of this invention is to provide means attachable to a gang plow, and adapted to so transmit the draft eilort as to properly balance thside lateral thrust 'Stil oi" the ground upon the plows. It consists of the features and elements described and shown in the drawings as indicated in the claims. e

ln the drawingsz-Figure l is a plan View of a device embodying this invention including the dott-ed outlines of a gang plow to which it is attached and the draft rigging for a four-horse team. Fig. 2 is a detail section taken asindieated at line 2--2 on Fig. l.

The draft equalizer whiehis the subject of this invention is shown in plan in Fig. l, attached to the 'traine of a gang plow which is indicated in dotted lines only, and consists of longitudinally extending members, A, each carrying a plowshare, B, and connected by transverse members, C, D and E. The draft equalizer consists ot a pair of bent bars, 1, l, and a pair of straight link bars, 2, 2, connected together and to the f member, E, of the plow trame, Thenlatter being of fiat bar stock set on edge serves as a convenient slide upon Which im y be clamped the brackets, 3 and l, whoseldetail construction is best shown in Fig. 2l The bracket, 3, is provided 'with a pivot-l4 bolt, 5, by which the ends of the links, 2, 2, are connected tot-he bracket, While clamping bolts, 6, serve to secure it at any desired position in the length of the member E.

The braelret, il, similarly clamped, and is pro-vided with a pivot bolt, i, by which the bent l rs. l, i,A are connected to the plow ramefaflhe ends o t` the links, 2, .2, this lettfree," are attached to the bent bars, l, by' short bolts, 8, d, which do not pass th rough the evener bar, F, which is carried between the members, l, 1, upon a pivot lio 9. The tree ends ot the members, l, l, teilig provided with a series auxiliary Sipeilcationox" Letters Patent. epnneaaon and novembel 25, 1911.

bolt holes, la, allow for lateral adjustment of the pivot point of the evener, F, for correotly accommodating the draft to the ,load i of the plow, such lateral adjustment being necessary in- View of the lateral thrust arisin'g from the reaction of the earth uponthe inclined blades, B, B, which lateral thrust is not entirely overcome by the usual land sides, B1, B1, applied to each of the plowshares. The links, 2, 2, are also providedu with a series of bolt holes, 2, designed to accommodate the bolts, 8, for making the connection between the members, l and-2., at different points in the length of the latter. Thus, there are provided three means of lateral adjustment of the pivot bolt, `9, with respect to the plow frame, namely, the slidability of the clamping brackets, 3 and 4t, upon the member, E; the adjust-ability of the bolts, 8, along the members, 2, 2, and the similar adjustability of the bolt, 9, along the members, l, il; so4 that by employing one or more of theseex-` pedients, almost any degree of adjustment may be obtained Within vthe desired limits. l claiini l. A draft equalizer comprising, in combi- I nation `with a frame, a pair of links pivotally connected to the forward end of said frame at pomtslaterally separated, the forward :end ot one link being pinned to the other link, said other link' extending beyond the point of attachment, and having its extending portion provided with a. series of apei`- tures, an evener bai' provided with a pivot aperture at its midpoint, and a pivot bolt extending through said aperture out thet evener bar andthrou'gh one ot the series ol apertures ot the link for connecting them.

2. fr draft equalizer comprising, in eombination with a frame, a pair of links 'piv otally connected to the Iforward end ot the said traine at points laterallyl separated, the forward end o one link being pinned to the other link, other link being bent beyond the pointoi attachment to extend substantially transverse to the direction of travel et the plow, andhaving its extending portion provided with a series of apertures, an e'i/ener bar provided with a pivot aperture at its mid-point, and a pivot bolt adapted to tend through said aperture of the evencr bar and through one 03"' the apertures ot the linlc for connecting them. i

3. A draft equalizer comprising in combilodged in any one of said apertures for fulnation with a frame, a pair of links pivotally 'criiining an evener bar.
